TWO- -WHEELED VEHICLE.

SPECIFICATION forming part of Letters Patent No. 399,650, dated March19, 1889.

Application filed January 16, 1888. Serial No. 260,907. (No model.)

To aZZ whom it may concern:

Be it known that I, IRA BROWN, M. 1)., of Milford, Iroquois county,Illinois, have in vented certain new and useful Improvements inTwo-VVheeled Vehicles or Road-Carts, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

Heretofore, although many have been the attempts, the effort to do awaywith the horsemotion in two -wheeled vehicles has to a greater or lessextent proved to be a failure.

The object of my invention is to produce a road-cart or othertwo-wheeled vehicle 'in which the horse-motion is entirely gotten ridof, and in which a steady even riding motion is experienced,substantially as hereinafter described, and as illustrated in thedrawings, in which Figure 1 is a side elevation of my improvedroad-cart. Fig. 2 is a plan View of the same. Fig. 3 is a detail viewshowing the arrangement of springs thereof.

Reference being had to the drawings, A A represent the shafts,preferably having their rear extensions curved downward and to the rear,and having their rear ends, a, terminating a suitable distance back ofthe axle B, as shown. Near the ends a of the shafts they are eachprovided with a vertical hole, a, therein, through which passes avertical stud, I), which arises from the arm 0. The arms 0 C are clippedtransversely to the axle just a little beyond the inner side faces ofthe shafts, and the rear ends, from which the ver tical stud b projects,are deflected outward slightly, so as to come under the holes a a ofsaid shafts. The forward ends, 0, of these arms extend a short distancetoward the front of the vehicle and then project at about right anglesout under the shafts, forming a fulcrum, cl, upon which the shafts restand rock. Secured to the upper surface of the shafts, about over thefulcrum d, are the leaf-springs D, which extend longitudinally to therear to and over the holes a in the shaft, where they are provided withan aperture in alignment with said hole, through which stud b likewisepasses. These leaf springs press upward against the heads of said studs.hen, therefore, the rider is in the seat of the vehicle and his weightis so adjusted as to bring his center of gravity to the rear of theaxle, the rear ends of said shaft naturally oscillate upward off of theends of arms 0 O and vibrate between the base and heads of the studwithout imparting the horse-motion thereto. Instead of leafsprings, asdescribed and shown, coil-springs could be placed around said studs,between the shafts and the heads thereof, and, if desired, between thebase of said studs and the shafts. I prefer the leaf-springs, however.

Clipped to the axle, preferablyimmediately over and by the same clip asfastens the arms C thereto, are the body-sprin gs E. These bodyspringsare preferably sort of -shaped that is, they pursue a horizontalstraight course toward the front of the vehicle until about beside thedash-board, where they are obliquely to the rear, in toward each otherbent back and pursue a course, preferably and upward at an angle of fromthirty to forty-five degrees. On the upper ends of these springs E issecured the seat F, and it is preferably secured to said springs so asto be adjustable longitudinally. To accomplish this adjustability in asimple manner, I provide longitudinal slots 6 in the side strips of theseat-frame and run a bolt, 6, up through suitable bolt-holes in saidsprings, which has a thumb-nut, f, on its lower threaded end, byloosening which the seat can be adjusted longitudinally within thelimits of said slots 6, and by tightening which said seat may besecurely held in such adjusted position.

Instead of the -shaped springs E, the ordinary ellipticalcarriage-springs or the platform spring could be used. I prefer thesprings shown, however. Secured to and depending vertically downwardfrom near the upper ends of the springs E or from the seat are the rodsG, 'which support the basket H. These rods depend vertically downwardfrom said seat to just in front of the axle, and are then bent forwardcorrespondingly and have the transverse floor-strips of the basketsecured to them. Their forward ends are suitably secured to a transversebar, h, which is held in the ends of the fiat springs g g, which latterare clipped to the axle independent of springs E, or, as I prefer,secured to said axle by the same clip as secures arms 0 and springs Ethereto.

If desired, a dash-board may be provided which can be secured to ironbrackets arising from the transverse bar It or from the flat spring g.

What I claim is 1. A two-wheeled vehicle provided with a suitable seat,springs for supporting said seat above the axle, and said axle, incombination with the shafts, the rear ends of which extend back of theaxle and have vertical apertures therein, and arms 0 0, having studs 1)rising from their rear ends, and having their forward ends bent at rightangles to its length, as set forth.

2. A two-wheeled vehicle provided with a longitudinally-adjustable seat,springs for supporting said seat above the axle, and said axle, incombination with shafts A, having their rear ends extended back of theaxle and provided with holes a therein, arms 0 O, and studs h, arisingfrom their rear ends, as set forth.

3. A two-wheeled vehicle provided with a suitable seat, springs forsupporting said seat, and axle upon which said springs rest, incombination with arms G 0, having studs projecting from their rear ends,and springs D, as set forth.

4. A two-wheeled vehicle having asuitable seat, springs supporting saidseat, and axle to which said springs are clipped, in combination witharms 0 C, as described, having studs 5 rising from their rear ends,shafts A, the rear ends of which extend back of the said axle andthrough which said studs pass vertically, and springs D, substantiallyas described.

5. In a two-wheeled vehicle, the combination, with the seat, of the-shaped supportingsprings, the axle, the springs g g, and the basket H,as set forth.

6. In a two-Wheeled vehicle, the combination, with the shafts, arms 0,having studs 1) and fulcrumal projections 61, and springs D, of theaxle, fiat springs g, springs E, the seat F, and the basket H, as setforth.

'7. The combination, in a two-wheeled vehicle, with the shafts, arms 0,having studs 1) and fulcrumal projections cl, and springs D, of theaxle, springs E, and seat F, said seat being provided with longitudinalslots in its side frames and secured to springs E by bolts andthumb-nuts, as set forth.

8. In. a two-wheeled vehicle, the combination, with the shafts and axle,of -shaped springs and the seat, secured thereto, said springs havingtheir lower ends clipped to the axle, pursuing a forward course asuitable distance, and then bent back toward the rear, extendingobliquely in toward each other and upward at a suitable angle, as setforth.
